Import Tips
• Classify the cesium iodide photocathode tube under 8540.89.00 as a photo-cathode valve, and include its technical specifications on the invoice
• If importing for research purposes, check if a research exemption or end-use certificate is available to reduce duties
• Ensure the tubes are packed in specialized containers to prevent damage during shipping, as CBSA may inspect for integrity
